Description Jack Ottofaro 2018-12-20 22:21:08 UTC

Description of problem:

The fluent-plugin-remote-syslog delivered with OCP only supports TCP. If you rsh into one of the fluentd pods you can see it here /etc/fluent/configs.d/dynamic/output-remote-syslog.conf:

## This file was generated by generate-syslog-config.rb
<store>
@type syslog_buffered
remote_syslog node-0.ottogeneric.lab.rdu2.cee.redhat.com
port 514
hostname logging-fluentd-k5j46
facility local0
severity debug
</store>

The fluent-plugin-remote-syslog itself supports TCP and UDP (see https://github.com/docebo/fluent-plugin-remote-syslog) however the fluentd configuration does not expose an environment variable to set @type in the plugin:

@type syslog_buffered - TCP
@type syslog - UDP
